To @ZZ whom it 4may concern:

Be it known that I, CmUS M. DAVIDSON, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of- Missouri, have invented certain new and useful Improvements in Ealing-Presses, of which the following is a specication.

My invention relates to improvements in baling-presses; and one of my objects is to obtain a maximum stroke of the plunger inA order to obtain a large feed-opening with a minimum stroke of the trip-lever.

A further object is to obtain a tensile strain on the mechanism employed to advance the plunger, and thus avoid the loss of power usually accompanying this operation w'henthe customary pitman is employed Aowing to said pitman bending more or less under the compressive strain to which it is subjected. Y

Other objects of the invention will hereinafter appear, and in order that said invention may be fully understood reference will now he made to the accompanying drawings, in

Figure 1 represents a broken plan view of a press embodying my invention, a portion of it being in section taken on line I I of Fig. 2. Fig. 2 is an enlarged side elevation of` the power end of the press. Fig. 3 is a vertical transverse section of the same, taken on line III AIII of Fig. 1. Fig. 4 is an enlarged broken side elevation of the rear portion of the press, showing the operation of a cam, toggle, and plunger forming part of the invention. Fig. 5 is a vertical transverse section taken on line V V ofl Fig. 2, showing lhow a pair of rails forming a guide-track are supported.

In said drawings, 1 designates a hopper through which hay is fed into the balingchamber 2, provided with the usual retainers 3 and connected to 'the power end of the press by a bed-plate 4, constructed of angleirons bolted at vtheir forward'ends to a gooseneck 5. Said gooseneck is secured at its top and bottom portions to a transverse frame 6, comprislng upright castlngs 7, cross-bars 8,

secured to the ends of the upright portions, and centrally disposed cast-iron blocks 9 and 10, secured between bars 8. Vertical portions 7 are provided at their lower ends with stubaXles 11, mounted in a pair of wheels 12, which, in conjunction with a pair of wheels 13,

mounted upon a rear axle 14, form portable supports for the press.

13a designates a trip-lever provided at its opposite ends with the usual antifricti'on-rolllcrs 14a and formedv integral with a centrallydisposed vertical shaftv 15, provided .at its upper end with an integral cross-head 16, to which a sweep 17 is secured to which the team is hitched. Shaft 15 is journaled in block 9 and the upper and lower portions of the gooseneck, said lower portion being provided with a tapering boss 18, which rests in a tapering socket 19 inthe central portion of block 10. The lower portion of shaft 15 is reduced to form a shoulder 19, which rests upon the lower portion of the gooseneck. The upper portions of the gooseneck and frame 6 are braced to resist the strains imposed thereon when the trip-lever is in operation by means of a brace comprising a pair of brackets 20, secured lside by side upon the bed-plate, tie-rods 21 connecting the upper ends of the brackets to the rear upper portion of the gooseneck and gas-pipes 22 inclosing the rods and abutting at their opposite ends against the brackets and the gooseneck. (See Fig. 2.) The upper ends of the brackets are braced by a transverse bar 20a, secured to rods 21 by taps 21a.

23 designates a pair of laterally-projecting arms formed integral with one side of the gooseneck.

25 designates a chain secured at its forward i end to a rod 26, secured at its forward end to a pair of bars 27, pivotally secured at their forward endsr by a bolt 28 to a pair ofbars 29, rigidly secured near their forward ends to-aA block 30, against the rear face of which rollers 14 are adapted tocontact, bars 29 being far enough apart topermit the trip-lever to 23 and bars 29 to prevent the latter from i swinging away from the trip-lever when one of rollers 14 is in engagement with block 30.

32 designates a roller interposed between the forward ends of bars 27 and journaled upon bolt 28.

33 designates a pair of parallel rails arranged on opposite sides of roller 32 and secured at their opposite ends to brackets 20 and an inverted-L-shaped casting 34, bolted upon one of the angle-irons formingthe bed-plate.

The rear end of chain v25 is attached to a pin 35, forming the pivotal point lofa toggle'36, comprising a casting 37, rigidly secured at one end to shaft 38 land pivotally secured at its opposite end to pin 35, and a pair of arms 39, pivotally secured at their opposite endsto order that the tension of spring 43 may be regulated.

Plunger 4() is caused to move forward 1n an f opposite direction to the block 30 and with increasing power by a cam 46, mounted upon Aa shaft 47, journaled at its opposite ends in bearings 48. Cam 46 has a low radius 49 at `one end, a high radius 50 at its opposite end,

andan intermediate radius 51, connecting 49,

and v50, as shown in Fig. 4. It also has a peripheral groove 52 for the reception of the rear portion of chain 25, secured to the cam by a hook-bolt 53.

54 designates a recess in the cam to prevent the latter from contacting with shaft 38 when 'occupying the dotted position shown in Fig.

-' 4. rllhe cam extends through a slot 55, provided in the casting 37 to prevent the cam from conflicting therewith.

`When toggle 36 is in the extended position shown by full lines, Fig. 4, all tendency of its becoming locked, and thus preventing the quick rebound of the plunger, is overcome by a retractile spring 56, attached at its opposite ends to an eyebolt 57 and a chain 58, which latter is attached at its lower end to pin 35.

'Eyebolt 57 is secured to the intermediate portion of a brace 59, extending from one end of hopper 1 for the support of the upper end of an arch 60, extending upwardly from the bedplate to protect the outside horse from con- `tacting'with the toggle when the latter swings back to the folded position shown by dotted linea-Fig. 4.

' In operation one of rollers 14a contacts with block 30 at the point shown by dotted lines, Fig. l, and as the trip-lever rotates it advances jsaid block, which is held in engagement with the trip-lever by arms 3l until bars 29 almost "contact 'with shaft l5, when the engaging Aroller v14a passes out of engagement with block "30. As'the block advances it straightens out toggle 36 through the instrumentality of "chain 25H and the cam over which said chain operates, and thus causes the plunger to advance and compress the charge of hay. The initial movement of the plunger will be comparatively fast and accompanied with but little power, because chain 25 is then pulling around the low radius of the cam; but as the plunger nears the end of its forward stroke its power is increased and speed ldiminished by the high radius of thecam rotating into l contact with chain 25. The instant the -trip- "lever disengages the block the plunger will rebound until it-contacts with stop-blocks 61,

owing to the expansive force of the conlpressed hay and the retractile power of springs 43 and 56. The forward and backward movements of chain 25, rod 26, and bars 27 will be in a direct line owing to roller 32 traveling between guide-rails 33, and in order that bars 29 may be brought almost in alincment with bars 27 when the latter are at the end of their forward movement the trip-lever shaft l5 is set to one side of the center of the bed-plate, as shown in Fig. 1, and in order to obviate the necessity of the front ends of bars 29 from swinging outwardly with the trip-lever far enough to exert much side draft the bearingsurface of block 30 is made suiiiciently long to prevent accidental disengagement of the contacting roller 14. The advantage of thus operating these bars in practically a direct line is obvious and requires no further explanation.

In order that block 30 may be adjusted to properly cooperate with the plunger and triplever, the forward end of rod 26 is provided with a plurality of bolt-holes 26 for the reception of bolts 26h.
